Brake Drum Replacement

A few modern cars still use drum brakes and, almost without exception, drum brakes are used on the rear wheels. The brake drum is attached to the wheel and rotates along with it.

Brake Flexible Hose

The flexible brake hoses attach the rigid metal brake lines to brake calipers and/or wheel cylinders. This flexibility allows free movement in the wheels and the suspension.

Brake Caliper Replacement

Disc brakes are commonly used on each wheel of a modern car’s braking system. Brake calipers are part of a disc brake system.

Brake Rotor/Disc Replacement

Brakes are located at each wheel to slow or stop the vehicle. Brake pads apply pressure to the brake rotors to slow or stop the vehicle.

Brake Wheel Cylinder Replacement

Brakes are located at each wheel to enable the vehicle to come to a complete stop. The brake wheel cylinder applies pressure to the brake shoes.

Clutch Replacement

The clutch assembly consists of a clutch disc, a clutch pressure plate, and a clutch release bearing. All these components are usually replaced at the same time.

Clutch Cable Replacement

The clutch cable provides a means to "break the drive" between the engine and the wheels. The engine spins constantly, but the wheels do not, so in order to stop a car's wheels without turning off the engine, the wheels have to disconnect from the engine.

Clutch Master Cylinder Replacement

The clutch master cylinder generates the hydraulic pressure necessary to operate the clutch assembly. The clutch assembly has two key functions: to transmit power produced by the engine to the gearbox and to disrupt that power flow when the clutch pedal is depressed.

Clutch Slave Cylinder Replacement

The clutch slave cylinder is directly attached to the manual transmission casing. When the clutch pedal is pressed, pressure generated by the clutch master cylinder is applied to the clutch slave cylinder.

Differential Drain and Refill

The purpose of the differential is to distribute engine energy to the axles so that the axles spin the wheels the right way at the right speed. The differential also allows the wheels to spin at different rates as a vehicle rounds a corner.

Clutch Pilot Bearing

The clutch pilot bearing connects the manual transmission input shaft to the engine crankshaft. The bearing allows the input shaft to rotate independently of the crankshaft.

Clutch Pressure Plate

The clutch pressure plate squeezes the clutch disk against the flywheel, which allows power (torque) from the engine to be transmitted to the manual transmission. .

Differential Oil

The differential contains gears and bearings that are lubricated by oil. Without this lubrication, friction can wear down the gears and bearings, causing them to fail.

Gearbox Oil

Gear oil is thicker than engine oil or transmission fluid and is formulated specifically for gearboxes, e.g.

Clutch Release Bearing

The clutch release bearing—commonly referred to as the "throw out" bearing—pushes on the pressure plate to disengage the clutch. .
